# Algorithms vs Codelet

Algorithms and Codelet both sit at 4.7 stars, but that hides the real split: 91% of Algorithms's written reviews are positive against 53% of Codelet's. Codelet's advantage is in-app purchases (none vs 1). On price, rating, ratings volume and update cadence there is nothing between them.

Both are free to download. Algorithms sells 1 one-off in-app purchase. Codelet asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.7 for Algorithms against 4.7 for Codelet. Both are backed by a comparable volume of ratings — 101 and 127 respectively. Written reviews are what separate them: 91% of Algorithms's written reviews are positive against 53% of Codelet's.

Algorithms ships an update every 6 weeks, Codelet every 2 months. The most recent releases landed on September 30, 2026 and October 2, 2026 respectively.
